FAQs on Motions of the Earth (Animated Video) Video Lecture - Class 6

1. What are the main motions of the Earth?
Ans. The main motions of the Earth are rotation and revolution. Rotation refers to the spinning of the Earth on its axis, causing day and night. Revolution refers to the Earth's movement around the Sun, completing one orbit in approximately 365.25 days.
2. How does the rotation of the Earth cause day and night?
Ans. The rotation of the Earth causes day and night because as the Earth spins on its axis, different parts of the globe are either facing towards or away from the Sun. The part facing the Sun experiences daylight, while the part facing away experiences darkness, resulting in day and night cycles.
3. What is the duration of the Earth's revolution around the Sun?
Ans. The Earth takes approximately 365.25 days to complete one revolution around the Sun. This is why we have leap years every four years, to account for the extra 0.25 days and keep our calendar in sync with the Earth's orbit.
4. How does the Earth's revolution around the Sun impact the seasons?
Ans. The Earth's revolution around the Sun impacts the seasons by causing variations in the amount of sunlight received by different parts of the globe. When a particular hemisphere is tilted towards the Sun, it receives more direct sunlight, resulting in summer. When it is tilted away, it receives less direct sunlight, leading to winter. The tilt of the Earth's axis causes the changing seasons.
5. What is the significance of understanding the motions of the Earth?
Ans. Understanding the motions of the Earth is significant because it helps us explain and predict various natural phenomena. It helps us determine the length of a day, the occurrence of seasons, the position of celestial bodies, and the measurement of time. It also aids in navigation, agriculture, and the study of climate patterns, contributing to our overall knowledge of the Earth and its place in the universe.
